We present the AC susceptibility, DC magnetization and specific heat measurements on an orthorhombic polycrystalline UAuAl sample. The results show typical cluster glass behaviors at low temperatures. To characterize the spin freezing state of this system, the static spin freezing temperature Ts, critical exponent zν and activation energy Ea are determined from the dynamical analyses of the AC susceptibility data.
